摘要： A method for reporting touch on a touchscreen includes detecting first touch data from the touchscreen corresponding to a first touch on the touchscreen; determining coordinates of the first touch from the first touch data; reporting the coordinates of the first touch at a first time; determining predicted coordinates of a second touch based on a linear regression of historical touch data; and reporting the predicted coordinates of the second touch at a second time, where the second time occurs after the first time.

摘要： A method of operating a display includes performing a non-synchronized touch scan pattern on a display with a controller coupled to the display. The non-synchronized touch scan pattern schedules touch scans independent of a refresh rate of the display. Upon the controller detecting a first synchronization pulse from a display controller coupled to the controller and the display, a first pulse-checking timer is started. Upon detecting a second synchronization pulse from the display controller and before the first pulse-checking timer expires, a first display refresh rate for the display is obtained from an interval between the first synchronization pulse and the second synchronization pulse. A synchronized touch scan pattern is performed with the controller, and is scheduled to avoid touch scans coinciding with refreshes of the display performed at the first display refresh rate.
